Installing non-Steam games on your Steam Deck is totally doable! First, switch your Steam Deck to Desktop Mode. From there, you can download and install any compatible game launcher (like Epic Games Store or GOG). Just download your game through the launcher, and you鈥檙e good to go. You can also add it to your Steam library as a non-Steam game for easy access in Gaming Mode.
Actually, you don't need to do much. Just enable Proton in your Steam settings for any non-Steam game you add to your Steam library. Proton lets you play games that aren't originally designed for Linux, which is what Steam Deck runs on. Easy peasy!
Honestly, why bother? Steam has everything you need. Stick to Steam games to avoid compatibility headaches.
